Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUTA | output | Output of amplifier channel A. Rail-to-rail output stage, swings to within 1 mV of V+ and V- with a 100 kΩ load. |+| 2 | -INA | input | Inverting (negative) input of amplifier channel A. Rail-to-rail input, common-mode range extends 500 mV beyond V- and V+. |+| 3 | +INA | input | Noninverting (positive) input of amplifier channel A. Rail-to-rail input, common-mode range extends 500 mV beyond V- and V+. |+| 4 | V- | power_in | Negative (lowest) power supply. Typically GND in single-supply operation; supports supplies as low as 2.5 V total (V+ - V-). |+| 5 | +INB | input | Noninverting (positive) input of amplifier channel B. Rail-to-rail input, common-mode range extends 500 mV beyond V- and V+. |+| 6 | -INB | input | Inverting (negative) input of amplifier channel B. Rail-to-rail input, common-mode range extends 500 mV beyond V- and V+. |+| 7 | OUTB | output | Output of amplifier channel B. Rail-to-rail output stage, swings to within 1 mV of V+ and V- with a 100 kΩ load. |+| 8 | V+ | power_in | Positive (highest) power supply. Single-supply operation from 2.5 V to 5.5 V (V+ referenced to V-). Bypass with 0.1 µF close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `OPA2340UAUA`++## CAD (KiCad official)++- Symbol: `OPA2340UA`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/opa2340ua-datasheet.pdf) (18 pp, sha256 `e75e687924f6aa75`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
